My invention has for its object a dispensei` more particularly adaptedto be used in connection with pulverulent substances such as talcumpowder, face powder,soap and the 15" like, and from which the dispensingof said substances `is effec-ted automatically.

The container preferably comprises a sta'- tionary cap-shapedv upperportion having an apertured flat bottom, and, below .this upper portionis a movable frame whose center'is provided withv a inemeshedwire-cloth.A This movable frame is operatively connected. to the coverof the container.v i

The subst-anceV to be dispensed is put into d the container through itsbottom portion from where itis pushed against the upper apertured partby a coil spring.

. Vith'this and other objects in view the invention consists intheconstruction, combination and arrangement of parts as will be morefully hereinafter described, illus'- tratedin the accompanying drawings,and pointed out in the hereunto appended claims. Inthe drawings,illustrating by way of eX ainple'several embodiments of the invention,Figure 1 is a'section andV Figure 2 a plan view in partial section vofthe container with open lid; Fig. Sis a plan view showing the details ofthe bayonet-joint of the movable 3@"lowerpart; Fig. 4 is section ofanother embodiment comprising a device whereby the outlet of thepowdertakes place only from the ycentral portionV of the container, and .inwhich the bottom part is provided with an Aup-turned ythreaded, rim;Fig. 5 is a plan viewv in partial section of the container shown in Fig.with open lid partially broken away Fig. G is a section through itslower part;

; Fig. v7 is-a plan view in partial section of a container .with piniondriven operating mechanism; Fig. 8 is a .vertical partial sectionthrough the operating mechanism shown y in Fig. 7 Fig. 9 is a plan viewin partial sec- 455 tion of a container in which the distributingmechanism is operated by a hinged handle; Fig.v 10 is a part verticalsection of the mechanims shown in Fig. 9;l Figs. '11 and 12uarepart.vertical sections illustrating an'operating mechanism comprising blocksmounted for sliding movement upon appropriately shaped slides. I

ln a preferred construction shown lin Figs. 1 to 3, the containercomprises a main body y l portion 1, a stationary cap-shaped upper part2, and a bottom part4,removably connectedv to the mainvbody portion bymeans of its rolled Vedge 5.

Connected for free rotary movement to the bottom part l by means of apivot 8,1 6.0"

provide a. disc 7 carrying a coil spring 6, the upper end of which isconnected to a groo-ved piston 9 provided with rubber 4packing 10i Thepowder or other substance to be distrib- 1 uted is laidvout upon theupper face 11 of 65 this piston which, under the action ofthe spring 6,is urged against the aperturedflat bottom of part 2. Preferably theupper face of the piston is suitably roughened or coveredkvvith asuitable vfabric or the like, so as to .hold the powder inplace andprevent its f following the movement of the frame 12, andthus provideafregular and unobstructed passage 'of the powder through the apertures3. As shown in Fig. ofthe movable framev 12is provided with teeth 13while its central portion is made up of ine-meshed wirefcloth 1/1, orthe like.

The frame itself is mounted for rotary move-y mentwithiii the groovel'provided in the 80 bodyof casingl so that the' same shall at all timesremain in'close Contact with the lower apertured face ofQthe'cap-shapedpart 2. Y. The hinged part 16 of the cover-17 is con-r nected to theframe 12'bymeans of a lug l18 85 extending from the latter and through aslot 19 provided in the main body portion 1 ofthe container; a slidingplate 2O is provided to close the slot`19 so that no spilling 1 ofpowder may occur through this opening. 90

The lower joint ofthe hinge 16 is rigidly fixed to the sliding plate 20.p The cover portion 17 is recessed in its'cen-` tral part so asto form areceptacle 21 to hold rouge ror a powder puff, or rlhis receptacle isclosed by the lid 22'wliich latter may, if desired, carry a mirror.4

In a preferred embodiment the closing and opening ofthe lower part ofthe container maybe effected as follows: the rolled edge 100 2, theinner periphery V 3 kindred articles.

5 of the bottom rplate 4 is provided with notches 24 and 25 (Fig. 3)adapted to engage corresponding ears 26 and 27 upon the main body. Thennow rotating the bottom plate, said ears will enter the groove formed bythe rolled edge 5, while the spring 28 penctrates into the cut-out 29securely locking the bottom plate in position; to unlock the same aslight pressure is exerted upon the spring 28 and the plate is turned inthe oppo- V site direction until the notch-es and 253 vare opposite theAears 26 and 27.

In a modiied construction illustrated'in Figs. l and 5 l have shown theholes provided in the upper cap-shaped portion occupying only arestricted area in the centr-al part thereof: In this way the powdeilwill not be wiped off 'by the powder puita and spilled outside thecontainer as often happens when the holes `are divided over the fullareaof the bottom of the cap.

In order to prevent the powder from becoming clogged beneath the plainportion of the cap 2, the movable fra-me ll2comprises helicoidallyshaped arms or scraper.,4 30, 8l {iX-ed -to sai-d frame (Fig. Thesearms, upon rotating the device, continuously return the Vpowder frombeneath the plain `to- 'B Wards the central apertured vportion of thecap 2. D ue .to the particul -r shape of the arms it will `be read-ilyseen that,l in order to return the powder to the central part, the

rotation of the dev-ice can tahe place in one direction'only. lith thisresult in View., l preferably provide upon the outer periphery of thefra1nel2ia series of saw teeth 32 cooperating with Aa. pawl 38 mounted-upon the hingefl of the cover 17 in such way, that, upon imparting aback and Yforth .movement to the latter, the trame will be rotated inrthe desired direction. In this embodiment also, the slot 19 is closed bythe slidingf 'plate 20.

f As shown in AFigs. 4t and 6, 'thefbottom plate 4t, insteadoibeingconnected to the main body portion l by bayonet oint may be Vfixedthereto by either *inner or outer thread connection.

.7 and 8 show in detail a modiied device w iich lmay be used incontrolling,` the movement of frame 12. In this device as in the othersthe loose powder is held `aga/in st the movable trarne 'by -inoa'ns of avpiston 9 (sce Fig. l) with ia `spring G vand carrying disc 7'. In this-case the movable frame l2 carries a flat extension 18 which is enclosedwithin a corresponding protuberant hollow part 60 ot the main body l.rlhis lboss is so dimens-ioned as to allow for 'free back fand forthmovement beiner controlled Aby means of a pinion vengaging in holes 100provided upon the extension 18.

The shaft llt) carrying the 'pinion 1410 eX- tends through an opening120 cut in the embossed part-60. The inner endcf theshaft is ycarriedupon a support 180, while its outer end is provided with a control knob150 of which the inner face is hollowed out so as t0 embrace the shapeof the protuberant part 60 and bear upon the recesses 170 formedtherein. ln this way the prominence of the knob is reduced to a minimum,While the free space upon its periphery 160 to be -gripped by thefingers is at the saine time incr-cased.

W'hen turning the button alternately towards the right and the left, themovable trame l2 `will describe a back `and forth movement and nause thepowder to escape through the holes '3 of the cap-shaped part 2.

F 9 .and l0 show in detail a further modiied control device for use on acontainer with a spring; pressed piston and plate 7 l(lsee ig. In themodified control device the bach and forth mov-ement ot' the movableframe 121s eliiected by means of a handle 230 which is connected byvahinge 16 -to a flat portion 1S eXtendiirg` from the fra-ine l2.

y 65. foraminous top wall, a lid for said container It is wellunderstood that the movable r0- tating or sliding frame inserted betweenthe substance which is to `be distributed, and a perforated plate, maybe either round, reotangular or any other shape desired and that suchplate may describe either a rotary, rectilinear, or any other -desiredmovement.

By turning the container upside down, the

spring may be dispensed with as in this case. the proper weight -of thepowder will be sufIic lowing claims.
